Did You Know?

The history of the word distend stretches back to the Latin verb tendere - a root whose kin have really expanded our language. To find evidence of this expansion, look to words that include "tend" or "tent"; many have "tendere," which means "to stretch, extend, or spread," in their family tree. Perhaps the simplest example is "tent," which names a shelter made from a piece of material stretched over a frame. You'll also find the influence of "tendere" in "extend," "tendon," "contend," "portend," and "tendency."

Word Root of distend

The Latin word tendere, meaning to “stretch” or “to spread,” and its form tentus give us the roots tend, tent, and tens. Words from the Latin tendere have something to do with stretching or spreading. A tent is a temporary shelter made from stretched out fabric. To distend is to stretch outward and swell in all directions. To extend is to stretch out. A tendon is a cord that connects a muscle to another muscle or to a bone and that stretches allowing a joint to bend. Something tense is stretched tight.
